●Vis/NIR spectroscopic observations of vertical structures of Jovian clouds
●Development of numerical models for the planetary atmospheres
Our lab is trying to create the systematic understanding of planetary atmospheres (including the Earth's) under the context of 'comparative planetology'. The field covers terrestrial planets (Earth, Mars, Venus), outer planets (Jupiter, Saturn, ...), interplanetary space, and exoplanets. All planets have their atmospheres. The word "atmosphere" here has wide meaning, in all altitudes from the troposphere to the exosphere. The lower layer is dominated by neutrals, coupled with surface and/or internal region. The higher layer is plasma world, directly connecting to and affected by interplanetary space and the Sun. The atmosphere is also controlled by gravity, temperature, history, sea, crustal activity, etc. A variety of physical and chemical processes occurring here decides the Environment of the planet. It can be guessed by the fact that our Environmental problems are closely related to "the Problems of our atmosphere".
All our researches are promoted by the development of state-of-the-art tools and techniques:
* Observational: New powerful instruments for space and ground-based
* Numerical: Advanced numeric codes and data analyses tools
By those driving forces, we have proceeded active researches and educations under international competition and cooperation, including the partitipations to international projects. Three groups are roughly composed with strong mutual coupling: (A) Modeling for sun-planets connection system, (B）Observation of planetary atmospheres/exospheres/magnetospheres, (C) Upper atmospheres - composition and luminescence. Those groups also provide main axes connecting Planetary and Space Physics Group, which consists of our lab, Planetary Plasma Physics Lab (PPP-Lab), and Planetary Plasma and Atmospheric Research Center (PPARC).
The Planetary Plasma and Atmospheric Research Center has two research sections:
• Planetary Spectroscopy Laboratory
• Planetary Radio-Physics Laboratory
These two research sections are collaborating and are pressing forward their research works to elucidate the environments and phenomena of the planetosphere using radio waves and light by means of observation.
